a .1 Claim. i

This invention relates to sharpening :devices such as pencil sharpeners, and in particular a device for forming points on crayons which, be cause of the fact that the material thereof fills up areas between cutting blades or sharpening devices, are not adapted to be sharpened on a conventional pencil sharpener.

Pencil sharpeners havebeen formed of various types and designs and whereas such devices are adapted for sharpening pencils and are also adapted for sharpening crayons to a lim ited degree, they are not-particularly adapted for pointin crayons continuously. "With this thought in mind this invention contemplates a crayon pointing device including a frame forming a head having a depending cup or base for receiving shavings, a bushing horizontally disposed in the head, a stud threaded in the side of the head opposite to that in which the bushing is positioned and located in alignment with said bushing, the stud being provided with a hand crank by which it may be rotated, and a ring having spaced knife blades extended therefrom secured to the end of the stud.

The object of this invention is, therefore, to provide means for forming a sharpener wherein oppositely disposed cutting blades carried by a stud threaded in a head of the sharpener are fed toward a crayon positioned in a bushing on the side of the device opposite to that in which the stud is positioned and means for rotating the stud whereby upon rotation of the handle or crank the cutting blades are fed toward the end of a crayon extended through the bushing.

Another object of the invention is to provide a device for forming points on crayons in which the feed for advancing cutting knives toward the end of a crayon is adjustable.

A further object of the invention is to provide a device for forming points on ends of crayons in which cutting knives are fed toward the end of a crayon held in one side of the device.

A still further object of the invention is to provide a sharpening machine for forming points on crayons in which the machine is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a substantially circular frame providing a head having a tab extended from the back for supporting the device on a, wall or the like, aligned bushings positioned at points on opposite sides of the frame, a stud threaded in one of said bushings, and having cutting knives extended from an end in the head and a hand crank on the end extended from the .head,;and a cupsecured by bayonet joints. to a .skirtdepending from the head.

.Other features and advantages or the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a vertical longitudinal section through the'improved crayon pointer.

Figure 2 is a vertical section through the head and cup taken on line 2-s'of Fig. rand with other parts omitted.

Figure 3 is a' plan view of the improved crayon pointer.

Figure 4 is a detail illustrating, on an enlarged scale, a mounting of the cutting knives, on the end of the stud.

Figure 5 is an end elevational view showing the positions of the cutting edges of the knives.

Figure 6 is a detail showing one of the pins and slots of the bayonet joints for holding the cup to the depending skirt of the head.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved crayon pointer of this invention includes a head formed with a circular band H3 having offset sections ii and E2 in opposite sides thereof and with a flange 13 extended upwardly from the back, and the head is provided with bushings M and it, the bushing It being positioned to hold a crayon and the bushing [5 being threaded to receive a stud it, on the outer end of which is a hand crank H.

The head is provided with a depending skirt [8 over which a cup I9 is positioned and, as illustrated in Fig. 6 the cup is is provided with a bayonet slot 28 and the outer surface of the skirt I8 is provided with pins 2| that are positioned to extend into the bayonet slot 2%. By this means the cup is may readily be removed to remove shavings therefrom and after the shavings are removed the cup may readily be replaced by inserting the slots 28? over the pins 2 l.

The bushing I4 is secured in an opening 22 in the offset section 5 l of the band it and when the body of the bushing is positioned the flange 23 on the outer end may be secured to the head by welding or the like.

The bushing 55 on the opposite side is threaded internally to receive the stud l5 and this stud is held in position by a lock nut 2 the stud being extended through an opening 25 in the offset section I2 of the band It.

The crank I7 is provided with a hub 26 and the hub is provided with a bore 21 into which a pin 28 on the end of the stud it extends and the crank is secured to the stud with a screw 29 that is threaded into a socket 30 in the end of the stud IS. The crank H is provided with a handle 3| that is mounted on a stud or arm 32 extended through the end of the crank or handle. The stud $2 is provided with a head 33 and the opposite end, which is threaded, is secured in the crank with a nut 34.

The crayon cutting elements include knives 35 and 35 that are provided with a base 31 and the base is secured in a transversely disposed slot 38 in the inner end of the stud IS. The outer ends of the blades are held by a ring 39 which is suspended from the end of the stud by the blades.

With the parts arranged in this manner acrayon is inserted in the bushing [4 with the end extended through the ring 39 and into engagement with the sharp edges of the cutting blades and as the blades are rotated by the crank handle H the screw threads on the stud feed the cutting knives toward the crayon whereby the crayon is sharpened or pointed. The excess material is deposited in the cup [9 and the cup may readily be removed and replaced in order to remove the shavings.

In use the crayon pointer is secured to the face of a wall or the like with a fastener extended through an opening 40 in the flap I3.

It will be understood that modifications, within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a crayon pointer, the combination which comprises a circular band providing a head and having ofi'set sections positioned at points in opposite sides, bushings positioned in the ofiset sections of the circular band of the head, one of said bushings having a bore for receiving internally, a stud threaded in the bushing threaded internally and having cutting knives extended from the end in the head, said knives being in the form of a V and having a ring carried by the extended ends thereof, and a hand crank on the end of the stud extended from the head and adapted to rotate the stud to feed the cutting knives toward a crayon positioned in the bushing on the opposite side of the head, said head having a depending skirt with oppositely positioned pins extended from the outer surface, and a cup having bayonet slots in the upper edge, said s10ts positioned for receiving the pins on the depending skirt of the head.
